部に出ている。Heater of underheat type holding furnace [Immersed in molten metal] This immersion heater is composed of a pipe-shaped heater protection tube that protects the d heating element and a heating element. Both ends of the immersion heater exit the furnace through the heater protection tube through hole.
従来、溶湯流出防止方法は、ヒーター保護管肖通孔の隙
間に詰め物を覆る方法が行われていた。例えばヒーター
保護管とヒーター保護管用通孔の隙間にセラミックファ
イバー等を詰め込む方法が行われていた。Conventionally, the method of preventing molten metal from flowing out has been to cover the gap between the heater protection tube port hole with a filler. For example, a method has been used in which ceramic fibers or the like are stuffed into the gap between the heater protection tube and the heater protection tube through hole.

−ることを１ｚ１徴どづるものである。The sealing method of the present invention is to provide a truncated conical hole extending toward the inside of the holding furnace around the heater protection tube through hole on the inner wall surface of the holding furnace, and to form a sealing part [2] in which carbon cloth is lined with asbestos cloth or ceramic fiber cloth. 1
Form the seal cloth into a megaphone shape, insert the end of the seal cloth on the large opening side into the hole, and fit the plug brick into the clear hole from inside the seal section. The heater protection tube is passed through the heater protection tube through hole and the seal cloth, and the end of the seal cloth on the small opening 1] side comes into contact with the heater protection tube. The purpose is to seal the protection tube through hole.

孔周辺の耐火物があまり傷まない。The sealing method of the present invention has the following characteristics, so that the heater protection tube can move freely without being restricted. Moreover, since the seal cloth has sufficient elasticity,
HatiJ? I never have anything to do. The pressure applied by the molten aluminum to the elastic sealing cloth ensures a sufficient seal. Also, the refractory around the lc1 heater protection tube through hole will not be damaged much.
傷んでも耐火物の交換が容易である。ざらに、炉に溶融
